Dual channel brushless motor driver KYDBL4875-2E 48v/24v 75A DCBL motor Intelligent Brushless Dc Controller

III. Product Features:

* Wide-range voltage input, 10-55V, max limit voltage 60V.

* Intelligent PID control loop.

*  Working  mode:   Speed  open-loop,  close-loop  control,  torque  close-loop  control,  position close-loop control.

* External potentiometer, 0-5V analog quantity or pulse command control mode, RC (pulse width signal outputted by the receiver of aeromodelling remote control) control mode.

* Safety forward & reverse control, four-quadrant operation, support regeneration.

* Enable control function.

* Maximum current control.

*  4-way  input  port;  the  function  can  be  defined  as  analog  input,  pulse  input  or  digital  input functions.

* 6-way digital (MOS tube open-drain) output, which can serve as the failure alarm status output of controller and can control the external relay to realize actions such as automatic disconnection of

power.

* Abnormalities like overcurrent, overheating, overvoltage and short circuit will start the protection function.

* LED status indicator.

* CAN bus communication, see the detailed communication protocol when using it.

* RS232 communication, see the detailed communication protocol when using it.

* USB communication, see the detailed communication protocol when using it.

Performance Index:

1. Power voltage: 10-55VDC.

2. At the ambient temperature 25℃, continuous working current 40A, transient current up to 75A 30S.

3. Minimum speed: 10 RPM in the speed close-loop mode; 1 RPM in the position mode.

4. Out +5VDC power (It can power up the encoder): 5V DC    20mA

5. Analog input range: 0-- 5VDC

6. Impulse input range: 500Hz—5000Hz (corresponding maximum speed)

[Note] The minimum impulse frequency may change along with the setting of maximum speed. 7. Input range of duty ratio 0％-- 100% (input frequency range f ≤1KHz, recommend to use the frequency of250Hz).

8. Temperature protection status: When the temperature is 70℃, the controller will reduce output by

overheating protection and will stop output when the temperature is 80℃.

9. Working temperature: -20℃-- +60℃.

10. Ambient humidity: Relative humidity≤80RH.

11. Boundary dimension: L * W * H = 190mm * 130mm * 77mm

12. Weight: 1000g

 Boundary Dimension:

Note: The bottom of controller shell has 4*Φ5mm holes for installation and fixing, and installation can be conducted in the horizontal direction.

Keep the controller away from dust and high temperature environment, and avoid unexpected contact. Keep sufficient space around the controller for ventilation and adjustment.

When fixing the controller, keep it from other heat sources. Ensure the controller works within the specified ambient temperature range.

Avoid to install the controller to devices excessively vibrating; if it is necessary, please take good vibration-proof measures.

Description of connection terminals
